In this post, we will write a C program to find the largest value in an array using pointers.

C Program to Find the Largest Value in an Array Using Pointers

In this program, all the elements of the array will be scanned using pointers.

Let's create a file named largestinarray.c and add the following source code to it:

#include <stdio.h>

#define max 100

void main()
{
	int p[max], i,n, *ptr, *mx;

	printf("How many elements are there? ");
	scanf("%d", &n);
	printf("Enter %d elements \n", n);
	for(i=0;i<n;i++)
		scanf("%d",&p[i]);
	mx=p;
	ptr=p;
	for(i=0;i<n;i++)
	{
		if (*mx < *ptr)
		{
			mx=ptr;
		}
		ptr++;
	}
	printf("Largest value is %d\n", *mx);
}

To compile and run the above C program, you can use C Programs Compiler Online tool.

Output:

How many elements are there? 5
Enter 5 elements 
10
30
50
20
80
Largest value is 80
